DDC123JH-7

Overview

The DDC123JH-7 is an NPN pre-biased small signal dual surface mount transistor from Diodes Incorporated, housed in a SOT-563 package. It features built-in biasing resistors with typical values of R1 = 2.2 kOhms and R2 = 47 kOhms. The device supports a supply voltage (VCC) of 50 V and a continuous output current (IO) of 100 mA. Power dissipation is rated at 150 mW, with an operating temperature range spanning -55°C to +150°C. The DC current gain (hFE) has a minimum value of 80.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated biasing resistors simplify circuit design

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration before purchase. Confirm that the component meets all relevant environmental compliance standards required for the target assembly process. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required in a SOT-563 footprint. Consider the 100 mA output current limit and 150 mW power dissipation rating against the specific load requirements. Verify input voltage limits to ensure operation within the specified safe operating area.

Part Context

This part belongs to the DDC series of NPN pre-biased dual transistors manufactured by Diodes Incorporated. The series offers various resistor combinations and packages to suit different design constraints. The DDC123JH-7 specifically utilizes the SOT-563 case style for space-efficient mounting.

Replacement Considerations

Direct substitutes include other DDC series parts with identical pinouts and electrical characteristics, such as DDC123JU-7-F or DDC123JCA-7-F, provided the package type and resistor values are compatible with the existing design.
